PROF. MILNE PRESENTS
PAPER TO SCIENCE CLUB
Improved Method of Vibration
Determination Discussed
How many vibrations are there in
the fiftieth wave of a vibrating tuning
fork! Or, how may the designer of a
water power plant determine the
amount of resistance or pressure in the
various tubes and pipes so as to regu
late the power which he desires to use?
These and many other questions of
similar nature are answered by Prof.
"W. E. Milne, of the mathematics de
partment, in his paper entitled
“Damped Oscillations,” which he re
cently read before the Science club.
By means of mathematical formulae
Prof. Milne illustrates in his paper how
the magnitude of damped, or deadened
vibrations may be obtained. The pa
per is the result of recent research work
in the field of damped hydraulic oscil
lation, a field in which, according to
Prof. Milne, no thorough investigation
has previously been made. Heretofore
the power of vibrations had only been
reckoned to the first power, but Prof
Milne goes beyond this and illustrates
how the power may be computed to any
given amplitude of a vibrating body.
Compares Various Solutions
Commenting on his work, Prof. Milne
said, “In most investigations of damped
vibrations, thfe damping iB, assumed
to be proportional to the first power of
the velocity. This assumption not only
permits an easy and elegant mathema
tical solution of the problem, but is
also frequently in close accord with
experimental evidence. There are, how
ever, a number of important problems
in physics and engineering where it is
necessary to employ a power of veloc
ity higher than the first. In some of
these problems the first power enters
explicitly, so that to include all cases
the differential equation must be writ
ten.
“The purpose of this paper is to pre
sent some of the salient characteris
tics of the solutions of equations and
to compare them with well-known solu
tions.”
Hopes to Publish Soon
Prof. Milne shows in his paper that
if motion could be run backward for
time there is a point where there is no
oscillation. Taking this as a basis he
illustrates how it is possible to deter
mine by the number of ocillations what
the given power of any given amplitude
will be. Thus one would be able to de
termine how big the oscillation would
be at the one hundred-twenty-fifth
wave of a tuning fork or the power of
any designated v^ave
The discoveries have much practical
application in the use and regulation
of surge towers or water power plants
in fengineering. Prof. Milne is putting
the finishing touches on his work and
hopes to have it ready for publication
soon.
AMERICAN TRAMP POET
(Continued from page one)
Quill and other societies of the type.
A small admission is to be charged to
defray the expenses of the lecture and
contribute perhaps to the poet’s outfit
should he consider one of the conven
tional Bort necessary to his appearance j
before a college audience.
The best known of Lindsay’s works
have been placed on the main reading
room desk at the library. Among them
are “The Chinese Nightengale,” “The
Congo,” “General Booth Enters Heav
en,” “In Praise of Johnny Appleseed”
(his latest), and a mass of material re
lating to him
There is more to Vachel Lindsay than
his exotic exterior. It is the rugged
ness and almost religious ferver of his
characteristic verses which have won
for him the very great praise which is
nowhere disputed and has only recently
been inflated by an almost triumphal
visit to England. He has many fads
and fancies. One of which is all-im
portant but has received over emphasis
in the past is his attempt to remove
poetry from the library reading room
and transport it back to its original
place around the fireplace to be intoned
or chanted. In the past ha has so
fashioned his verses to lend themselves
to his own peculiar way of rendering
them. Prom “The Congo" the follow
ing colorful lines are particularly il
lustrative of this tendency:
"Pat black bucks in a wine-barrel room,
Barrel-house Kings, with feet unstable,
Sagged and reeled and pounded on the
table—
Pounded on the table
Beat an empty barrel with the handle
of the broom,
Hard as they were able,
Boom, Boom, Boom.”
It is said that Lindsay is coming to I
be a bit ashamed of his past as a de- !
claimer and a chanter and very seldom \
does it any more. Perhaps he may be
prevailed upon to come back to it here
in Villard on the seventh. The choic- \
est bit of all is his “Kallvope Yell” !
which should fit in well with the j
acoustics in Vilard hall. Here is part
of it which indicates something of the
sheer abandon of the thing:
“I am the Gutter Dream,
Tune maker, born of steam.
Tooting joy, tooting hope,
I am the kallvope;”
It is seemingly necessary to intone
“Kalliope” as it is intoned by circus ;
crowds and not by Webster which is
doubtless a fault or would be a fault
in another poet- But one eritie said >
of “In Praise to Johnny Appleseed"
that it was as full of faults as a sieve
is of holes but was never the leas very
great in its entire conception.
FLOWER CAMPAIGN AIDED
Portland School Children Show Inter
est in Wild Plant Life
Letters full of real human interest re
ceived by Professor A. B- Sweetser, head
of the department of botany, from chil
dren of the Couch school of Portland
show the great interest which he has
aroused in Oregon’s wild flowers and
their preservation. In a campaign to
organize societies for the care of
flowers, similar to the Audubon bird
. societies. Professor Sweetser has en
1 deavored to interest the younger school
children by giving lectures illustrated
with slides. The need of a flower pro
tection society was foreseen in the east
and an organization formed, which now
looks after the flowers along the high
ways and in the parks.
Financial help is greatly needed now
to provide colored plates to be used in
lectures for children, young people, and
adults. Several persons are interested
in this flower preservation movement
which was begun by Professor Sweet
ser.

Close Cooperation Desired
Dean Fox declared herself to be eager
to see student government instituted on
the Oregon campus and expressed the
hope that this governing; would take
the form of a close cooperation between
students and faculty.
“I can see no reason why the students
should not have student government if
they want it,” declared the Dean. “I
am confident that the administration
and faculty would endorse it as soon as
the Associated students and the student
council are ready to assume the respon
sibilities whcih would be incumbent
upon them.
“The ideal arrangement, it seems to
me, would be a close cooperation be
tween students and faculty. I should
like to see greater student initiative
together with faculty approval in place
of faculty initiative and student ap
proval,” she continued.
Some Regulation Needed
Asked -whether she believed that an
installation of student government
bring abolishment of the social and dis
ciplinary rules at Oregon, Dean Fox
said that she could not anticipate such
procedure- She wishes university wo
men to be free from boarding school
supervision, but feels that they can
never get away from regulations where
there are so many living together.
“There must be law and order in any
group,” she pointed out, and she hopes
that the social life, especially the danc
ing, at the University will never be
come a dissipation. She has always felt
that social life should consist of normal
recreation and not dissipation.
“I should like to express the most
cordial indorsement of every effort
made to bring in the honor system.”
she continued. “I am impressed with
the fact that the students are taking
time to deliberate before adopting a
svstem which involves such responsibil
ity.”
DOUGLASS WRITES ARTICLE
Algebra Test Described in December
Number of Education Periodical
The December issue of the Journal
of Educational Research, the outstand
ing periodical in the field of education,
contains an article by Prof. H. R. Doug
lass of the school of education descrip
tive of his algebra tests which were
printed in a monograph by the Univer
sity last year.
The tests which provide a method for
i checking the effectiveness of teaching
and the measurement of power in the
subject, are recommended by the Uni
! versitv bureau of edncational research
and are used in high schools of the
state. Prof. Douglas is now collecting
information and material preparatory
to revising and adding to the tests
which he has devised.

sity.
